Hi, I was wondering if someone could help me out. I recently purchased the game Magicka, but then sadly realized that I could not play it. I was also upset because I had just purchased 2 new gigs of RAM. I was hoping that would solve some of my gaming issues, but I was wrong. My graphics card sucks. So, I researched one that I really like and really want to get, but my computer's output of watts is not nearly enough to supply my graphics card. The graphics card I'm looking at is the EVGA Nvidia e-GeForce 8800GTS 320 MB PCIe Video Card:

your onboard vid is crappy that's primarily why you're having gaming issues. your cpu is not far behind either but you can atleast buy a new gfx card and psu which will improve performance now and you'll be able to move them over to a new build if you decide to do that.
